CLIPPER KEEPER.

To all ywhom 'it may concern.'

Be it known that I, FREDERIC H. RAUH, a citizen of the United States,residing at South Orange, Essex County, New Jersey, haveinvented-certain new and useful Improvements in Clipper' Keepers, ofwhich the following is a specification.

My invention relates to keepers or locking means for keeping closed themembers oi jawed tools, and the like, so as to prevent the jaws fromspringing apart or opening when the tools are not in use. And myimprovements are directed to means whereby a simple and ehicient formof-spring keeper is provided, which will ei'iectually lock Athe tool inthe closed position, and when swung out of locked position will itselfbe locked in a .iixed but detachable relation to the part of the toolwhich carries it.

I have illustrated and will describe the improvements as applied to apair of orange clippers, but it is obvious that the principle canbe/used for other cutters, jawed tools, and the like.

In the drawings Fig. l is an eleva-tion of a pair of clippers showing myimproved clip in locked position thereon, the unlocked position of theclip being indicated by broken lines; Fig. 2 is a detail, on an enlargedscale, of the keeper and its supporting lug; Fig. 3 is a sectional viewon the line 3 3 of Fig. 2, looking to the left; Fig. et is a detail ofthe supporting lug; Fig. 5 is a sectional view of the lug on the line5-5 of Fig. 4L, looking to the lett; Fig. 6 is an edge view of thespring keeper, taken as looking to the lel't on Fig. 2; and Fig. 7 is across sectional View of the same, taken as looking down on the line 7 7ot Fig. 6. Figs. 2 to 7 inclusive are on an enlarged scale as comparedwith Fig. l.

In all the iigures similar parts are designated by similar referencenumerals.

A conventional pair of clippers is illustrated as provided with shanksl, 2 normally urged apart by a spring 3the shank l being provided with akeeper carrying lug 4l, while the shank 2 is provided with a keeperengaging hook 5.

The lug i is provided with two opposed euplike depressions 6 6; and itis also provided, preferably on one side, with groove like depressions7, 8, disposed at an angle to each other.

The keeper or hasp 9 is preferably formed of a loop of' resilient sheetmetal, from the body of which two lugs 10-10 are'struck inward, so thattheir free ends will n ormally fall within the sockets 6-6, into whichthey may be passed by springing the keeper over the lug 4. The keeper 9also has a projection Il formed upon its inner side by pressing in themetal oit' the keeper, and this projection is adapted to register withthe depressions 7 and 8 in the-lug il. as the keeper is swung around thelug, so as to retain the keeper in the positions shown by the full andthe broken lines in Fig. l, as may be desirable,l the elasticity of thekeeper 9 allowing the projection l1' to ride up out of the depressionswhen the keeper is forcibly swung-around in either direction, the lugsnapping back into whichever of the depressions 7 and 8 with which it isbrought into register.; When the keeper is swung into locking positionwith the hook 5, as shown -in Fig. l, it will be held against ordinarydisplacementby the projection ll registering in the depression 7 andwhen ,it is swung out of locking' position and into the positions shownby the broken lines in Fig. l, it will beheld in that position by vtheprojection l1 registerk ing with the depression 8, and will offer nointerference with the hook 5, or with the shank 2 of the cutter intheordinary use of the tool.

It should be .noted that the conforma-r tion of the lugs l010 of thekeeper is such that the drag of the hook 5 againstl the keeper, whenthey vare in the position shown in F ig. l, will causethe thrust ot" thelugs toy be against the wall of the sockets 6-6 at an angle which willcause the lugs to grip the walls of the sockets and hang to the lug et,insteadof riding out ofthe socket, as might be the case if the lugs10-10 were disposed at-right angles to the body oi' the keeper 9, orwere bent rearwardly. In practice, it is found that this formation givesa very dependable grip to the keeper on the lug and eiiectually preventsits displacementby the ordinary expansive force of the spring 3.

The convenience and efficiency of my improved orm of clipper will beappreciated by those accustomed to the use of clippers, and like tools,wherein keepers of the ordinary loop style, or similar non-lockabletypes, are used. Keepers of the classes just lllf) l mentioned areobjectionable -iii that they constitute loose or swinging elementsattached to one shank of the tool and likely :to vcome in contact withthe othersliank of,

the tool, or itsv appendages at an .improper time, perhaps catching theoperators hand between them, or being caught by twigs .orf

Vcombination, with one of such elements, of liasp engaging means, andwith t-he other of said elements of an integral carrying lug providedwith opposed, lateral sockets, and a resilient hasp mounted on the lugand'pro- .vided with integralv projections constituting t meanscooperating pivotally with the carrying` lugs sockets.
